摘要
采用气相色谱和质谱法对取自于云南丽江、西藏米林和波密地区的高山松松脂的化学特征进行研究。发现它们含有8％～15％△~3-蒈烯,这在中国松属松脂中是罕见的。同时发现它们与云南松和油松松脂的化学组成有明显不同。此外还检定出中国松属松脂中过去从未检出到的湿地松酸。
This paper studies first chemical characteristics of P. densata Mast. oleoresins from Lijiang of Yunnan, and Milin and Bomi of Tibet using gas chromatography and mass spectrometry. As high as 8%-15% Δ3-csrene, which is very rare in Chinese pine species oleoresins, is detected in the oleoresins. And their chemical compositions differ from that of oleoresins from P. yunnanensis France, and P. tabulaeformis Carr.. In this study communic acid is identified, which has not been detected in oleoresins from all Chinese pine species before.
